效果

Unity

首先是编写弹窗类的属性，用于设置弹窗信息

using System;
public class Dialog
{
    public string title;
    public string msg;
    public string[] buttons;
    public Action<string> onEvent;
    public Dialog() { }
    public Dialog(string title, string msg)
    {
        this.title = title;
        this.msg = msg;
    }
    public Dialog(string title, string msg, string[] buttons)
    {
        this.title = title;
        this.msg = msg;
        this.buttons = buttons;
    }
}

接着编写android代理类，安卓通过代理调用unity的回调

using UnityEngine;
public class AndroidDialog: AndroidJavaProxy
{
    Dialog dialog;
    public AndroidDialog(Dialog dialog) : base("com.unity.mylibrary.AndroidDialog") 
    {
        this.dialog = dialog;
    }
    public string GetTitle() { return dialog.title; }
    public string GetMessage() { return dialog.msg; }
    public string[] GetButtons() { return dialog.buttons; }
    public void OnButttonEvent(string title)
    {
        dialog.onEvent?.Invoke(title);
    }
}

然后传递代理类到android并打开弹窗

public class AndroidHelper
{
    public static void ShowDialog(Dialog dialog)
    {
        if (dialog.buttons == null || dialog.buttons.Length == 0)
        {
            Debug.LogError("必须有结束按钮才可显示弹窗");
            return;
        }
        var unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        var current = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
        var androidDialog = new AndroidDialog(dialog);
        current.Call("AndroidDialog", androidDialog);
    }
}

JAVA

编写代理类的接口

package com.unity.mylibrary;

public interface AndroidDialog {
    public String GetTitle();
    public String GetMessage();
    public String[]GetButtons();
    public void OnButttonEvent(String title);
}

显示AlertDialog

package com.unity.mylibrary;
import android.app.AlertDialog;
import android.content.DialogInterface;

public class AndroidDialogHelper{
    public static void Show(android.app.Activity context,AndroidDialog dialog){
        String[] buttons = dialog.GetButtons();
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setCancelable(false);
        builder.setTitle(dialog.GetTitle());
        builder.setMessage(dialog.GetMessage());
        builder.setPositiveButton(buttons[0], new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                dialog.OnButttonEvent(buttons[0]);
            }
        });
        if(buttons.length>1){
            for(int i=1;i<buttons.length;i++)
            {
                builder.setNegativeButton(buttons[i], new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        dialog.OnButttonEvent(buttons[i]);
                    }
                });
            }
        }
        builder.create();
        builder.show();
    }
}

最后在Activity类添加上AndroidDialog

package com.unity.mylibrary;
import android.os.Bundle;
import com.unity3d.player.UnityPlayerActivity;

public class AndroidActivity extends UnityPlayerActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    public void AndroidDialog(AndroidDialog dialog)
    {
        AndroidDialogHelper.Show(this,dialog);
    }
}

测试

using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{
    void Start()
    {
        var dialog = new Dialog("警告","快给我充值",new string[] { "好的"});
        AndroidHelper.ShowDialog(dialog);
    }
}
